I have another weird experience with network init script. My laptop runs sid
and kernels 2.4.x.
With kernel 2.4.3 my laptop boots normally (as usual), and kernel detects
the network card, etc.
With kernel 2.4.5 (and later kernels) ifconfig lo 127.0.0.1 hangs. I've
strace'd it and it hangs in:
[...]
ioctl(4, 0x8916, 0xbffffa1c) = 0
ioctl(4, 0x8913, 0xbffff95c) = 0
ioctl(4, 0x8914,
and I have to reset the laptop.
The same trace is applicable to 2.4.3, but the program ends successfully:
[...]
ioctl(4, 0x8916, 0xbffffa1c) = 0
ioctl(4, 0x8913, 0xbffff95c) = 0
ioctl(4, 0x8914, 0xbffff95c) = 0
_exit(0) = ?
Any hints?
